Pharrell Williams Auctioning Off That Crazy Grammys Hat for Charity

If you liked the enormous, eye-catching, vintage Vivienne Westwood hat that Pharrell Williams wore to the Grammy Awards, here's some good news: You can buy it!

But you might have pass your own hat around to raise the funds.

Williams, 40, has put the stylish cheapeau up for auction on eBay, with all proceeds benefiting From One Hand to Another, the charity founded by the musician to help underserved youth.

It's going to cost you, though, as the top bid is already $10,500. Bidding continues through March 2.

Williams advertised the auction on Twitter, posting a photo of himself wearing the hat along with the note, "Hey @Arbys, you want my hat? Now's your chance" – a reference to the fast-food chain's amusing Tweet on Grammy night, asking Williams for its hat back.

The eBay listing reads: "Now is your chance to own a piece of pop culture history! Bid on Pharrell Williams' Vivienne Westwood 'Mountain' hat that was one of the biggest hits of the 2014 GRAMMY Awards."
